Update bower.json

The version specified in the bower.json of package converse mismatches the tag (0.5.2 vs 0.5.0)

Tests pass locally though

Testing requires jasmine and require which are not bundled anymore but instead
installed via bower.

Instead, expose only the initialize and onConnected functions.
Updated the tests to work with this.

Messages sent between two Gtalk accounts weren't being received.

Users without roster contacts didn't have XMPPStatus.initStatus called and
therefore had a default status of offline.

Fixed this by setting the status to online from the start. The fetch command
will get the true status from localStorage (if available).

Made sure that the rest of converse's onConnected code is called in the
callback from fetch (so that we know the user's status is correct).

Updated and fixed tests.

On Plone I've been having issues with event handlers being registered on
elements not yet added to the DOM not being called.

Also, get rid of the misnamed $parent attribute on the panels. Instead, pass in
the correct parent to initialize.
